lie it known that l, ,lonx .lfl. Donor a citizen of the United States,residing at Portland, in the county of Cumberland and State of Maine,have invented certain new and usetul Improvements in lllachines forOperating upon Coins; and l do hereby'declare the following to be afull, clear. and exact description of the invention. such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to in ms for operating upon coins or otherarticles of disk tornn to separate them troin a mass and deliver themfrom the machine in succession.

The presentinvention is especially useful for separating; coins otditl'erent denominations from an iinliscriniinate mass and deliveringthem individually to devices where in they are subjected to furtheroperations such as sorting and countin one object of the invention is toprovide certain new and useful inuu-rwements in the construction andmode oil? operation of machines of the above character tor the pur poseof expediting: the separation of the coins and e'ltez'etinc theirdelivery flatwise in an orderly and substantially continuous procession.

Another objectof the invention is to ettect the separation ofindividual, coins or other articles, from a mass, by successive stages,each, of which consists of reducing thesize of the mass operated upon byseparating therefrom a smaller portion.

A further object of the invention is to provide improved means forfeeding the coins rapidly from a receiving hopper to a separating deviceand for insuring against the liability Of the coins becoming massedtogether in the hopper in such a manner as to interfere with thedeliveryoit the coins therefrom.

With these objects in view, one feature of the invention consists in theprovision of a hopper for receiving the mass of coins. a coin separatingdevice and means for successively transferring limited quantities of thecoins from the mass in the hopper to the separating; device.

Another feature of? the invention resides in the rotary distributingplate or disk and the cooperating" elements which comprise theseparatingdeviceand which effect the separation and individual delivery of thecoins.

Still another feature or the invention con 1 prises the agitating devicewhich serves to prevent blockading; or clogging of the coins in thehopper and to insure the master of a substantially equal quantityot'coins from the hopper to the separating device at each operation ofthe transferring; means.

lo the 210C011!pllSlillflellt or these and such other objects as mayhereinatter appear, the invention resides in the devices, combinationsand arrangements ot parts hereinafter described and. subsequentlydefined in the appended claims and which possess 2ltlVt1l1- tagesapparent to those skilled in the art. I

l The various teatures ot the invention will be readily understood trointhe following description and the accompanying drawings illustrating thepreferred the invention, in which A Figure 1 a view in front elevationof the machine showing also a sorting device to which the coins may bedelivered; Fi m EZ a top plan view. partly in section on l ne f22 oiFig. l shcwvinn' particularly the driving mechanism; Fin. is a view invertical longitudinal section oi": the hopper and its supporting coluinnshowing the agitating device and the transferring mechanism; Fig. 4: adetail view looltino at the top of the separating; device and showingalso portion of the hopper: l 5 is a view in rear elevation. partlybroken away. of the parts shown in Fig l; Fin. 6 is a top plan view ofthe hopper and the separating dcvicez Fi gz 7 is a detail sho ing asection on line T-'-7 ot 4:: 8 showing a section on line F?-8 and Fig. 9is a p rspectiveview separaing; device. I

ln the pri [1 ed embod of the invention illustrated in the drawings, themachine comprises. in general. a hoppe 12., in which the mass of coinsis deposited and which is support-ed by hollow COll -il'li'l is, risingfrom a base 16; a coin separating device 18. which supported b a post20. projecting: upwardly from the base to. and is provided with a pocketor receptacle into which the coins are lelivered from the hopper and aninclined rotary distriou in."

ot Fig. 41; out the corn t k or separating; plate which forms one sid oithe pocket 22 and which operates to s parate the coins from the ma inthe coin pocket and to cause them to be delivered successively from thedeiuee; a coin chute embodiment of is a detail 26 for conveying; thecoins from the hopper 12 to the coin pocket 22; a plunger 28. within thehollow column let, which is adapted to move upwardly through the hopperto raise a limited number of coins above the mass in the hopper anddischarge them into the chute 26; means including the vertical rods 30,32 and 34 which project through the walls of the hopper adjacent theplunger 28 and. are actuated by the movements of the plunger to agitatethe coins in the hopper: and means for operating the plunger and forrotating; the distributing plate.

In the present machine, thus briefly described. substantially the samenumber of coins are delivered into the coin chute 26 and guided therebyto the separating device at each operation of the plunger. Thisintermittent transfer of coins from the hopper to the separating deviceoccurs with sutficicnt frequency to maintain the proper quantity in thecoin pocket 22. A great deal of difliculty has heretofore beenexperienced in coi'itrolling the feeding of coins or similar articles"from a hopper. in which a large quantity is contained; a satisfactoryand uniform delivery being seriously lntertered. with by the tendency ofthe coins to mass themselves together in such a way as to check theflow. The herein described mode of feeding the coins from the hopper hasproved to be an exceedingly effective way of overcoming the tendency ofthe coins to become blockaded and for insuring: the feeding; of thecoins at a substantially uniform rate irrespective of the quantity inthe hopper. The coin pocket oi the separating device in effect. asecondary hopper which is kept replenished from the main hopper so thatjust the proper working quantity of.

coins is maintained in the mass in. the pocket from wh ch the coins areseperated by the distributing plate. In the main hopper the cloggingorblockading ot' the coins prevented by the action of the agitatingdevice. while in the coin pocket of the separating device the tendencyof the coins to become blockaded is minimized because of the lessernumber of coins confined therein and further by the construction andarra mentof the stationary rewaininp wall of the pocket and by theoperation of the rotary distributing plate, all of which will behereinafter described.

The hopper 12 which is supported by the column it is substantiallytunnel-shaped. being formed by walls which flare outwardly and upwardlyfrom one side of the hollow supporting column and merge with asemicylindrical vertical wall 36 which is an eX tension of the oppositeside of the column. The coins are poured in at the open top of thehopper and are intermittently fed from the hopper into the chute 26 bythe plui'iger 28 which is moved upwardly, through an opening in thebottom of the hopper, to tho levelot the top of the chute. The slopingwalls of: the hopper cause the coins to settle toward the bottom. and asthe mass diminishes, the coins will gradually slide toward the recess orpocket 38 which is formed above the plunger by the wall 36, so thatthere will always be a mass of coins directly over the plunger so longas any coins remain in the hopper. The plunger which is entirelyretracted within the hollow column. when in its lowermost position. ispartially housed by the semi-cylindrical wall 36. as the plunger movesup and down in the hopper. This wall 36 provides lateral support for thecoins which are carried upward by the plunger and is 'lorn'ied at thetop with an iiipcninp; it) to permit the passage oi the coins into thechute 26 when the plunger is at the top of its stroke. The top face ofthe plunger is inclined toward the chute sutficiently to cause the coinsto slide oil the plunger and into the chute when the plunger reaches thetop oi. its stroke. and the inclination ot the chute is such that thecoins will slide down the chute by gravity and be deposited in the coinpocket of the separating device. Because of the inclination of the topface of the plunger toward the wall 36. the coins will tend to slidetoward this retaining wall as they are elevated. rather than back intothe mass in the hopper and consequently a greater number will be raisedby the plunger than would 1 the ca e ll its top l :c was level. For thepurpcse oi tacilitatingr the release into the chute oi" the coins whichare raised by the plunder. the upper face of the plunger is providedwith narrow parallel grooves 42. whch extend toward the chute and serveto reduce any tendency of toe coins to adhere to the top of the plungerdue. tor example. to dampness or the pixsencc ot'i'oreig 'n substance onthe faces of the coins l t necessary, in order to prevent hloclc ad ngr.or clogging of the coins in the hopper. and to insure that the flow oicoins from the mass in the hopper into the recess or pocket 38. as theplunger recedes. will not be interfered with. to provide suitable meanstor agitating the coins at each operation of the danger To this end thevert cally disposed agitating rods 3!). 3i and 34. are arrangedalongside ot' the column it with their upper ends projecting through thebottom of the hopper. As the plunger rises. th rods are pushed upwardlytogether tllIfOtlQl] the mass of coins and on the downward. movement ofthe 'ilun qer. the rods are withdrawn. Thus the for mation of the massis distributed each time coins are "fed from, the hopper and the coinsare not permitted to arrange themselves so as to prevent the settling'or flowingot the mass to fill up the cavity let't by the removal of thelast group of coins by the plunger. The agitating rods are locatedcloseto the column 14, the rods 30 and 32 being arranged on opposite sidesthereof and adapted to rise in the hopper closely adjacent the cornersformed by the j'un ction of the wall 36 with the walls of the main partof the hopper. wh le the rod 3 L is equidistant from the others andarranged. to operate in .a planeopposite the pocket 38.

The tops of all of the agitating rods normally project slightly abovethe bottom of the hopper. shown by dotted lines in Fig. l. The rods 30and 32 which are rigidly connected by a cross bar 4:4 extend throuizhand are guided by bearings 4-6 on the column 1st. and are si'ipported byspring-s 48. whfch surround the rods below the cross bar and rest uponthe upper end of the bearings -16. while the rod 3-iextends through alug 50 formed on the cross bar and through a lug 52 lillO ltl'tllig froma block 54. which is secured tothe lower end of the plunger. andprojectsthrousrh a slot in the column 14;. the rod being; supported bythe engagement of the lug 50 on the cross bar with a. collar 58 which isfixed on the rod. On the upward movement of. the plunger. the lun 52slides upward on the rod 34- and after thebloek 54- has come intocontact with the cross bar 44 the three rods are raised in unison topoints about midway hetweenthe bottom and the top of the hop ')er. 0nthe downward inovemeiuzo the plunger the rods will ordinarily be held intheir elevated positions by the pressure of the, mass of eoinsaeainstthein unt l the lung 52 on the blocl; 54 engages a head 60 wh ch isformed at the lower end. of. therod 34 when the three rods will beretracted to- ,rether from the hopper. The'springrs serve to cushion thedownward movement of-.the agitating device and prevent undue noise andshock froin resulting therefrom. while a. spring 2 surrouni'l npr therod 34 above the collar performs a similar function on the upwardmovement of the agitators. It will be observed that when the plunger isin liSPXtIGIDQ lower position the sprinir 48 will be compressed and therods w'll be retracted slin'htlv more than shown in Fig; 1. thuspermitting an unobstructed How of coins along the bottom of the hopperand over the top face of the plunger.

The separating device 18 to which the coins are led by the chute 2t;cin' prises the inclinedfrotarv distributing plate or dist; 24. and astationary disk-shaped head 6-ion which the distributing plate supportedand which .is providei'l with a. peripheral coin retaining wall '66which partly surrounds the head. A peculiarly shape-l curved wall 68which is an extension of the wall 66 serves, inconjunction withthe pisteitself, to form the pocket 22 (Fig. 8) into which the coins are delvered from chute 26. while the peripheral wall {56 prevents the escapeof the coins laterally. from the separating devi e as they are beingrotated with the distribiufiine plate until they are ready to be finallydelivered from the machine. The angle of inoliinltion of thedistributing; plate ill egreater than the angle of normal rep se of hecoins by an amount suli'icient to inst 3. the sliding of the coins bygravity toward the lower part of the plate.

For the purpose ofpreventing the escape of the coins between the end of the walltiS,adjacent to the block 82 and the discharge chute 26. the cylindricalface of the block 82- is extended upwardly at this point by means of thewall 88 as shown in Fl 5 and 9. I

In order to effect the separation of the coins from the mass in the coinpocket. ,2.

the upper surface of the distributing: plate is provided with aplurality of radiating feed strips or ribs 90' which serve to distributethe coins from the surface of the distrilnrting' plate. lhese feedstrips project above the surfaceof the plate an amount equal, to orslightly less than the thickness of the thinnest coin to be operatedupon, which is the (nine. and they extend outwardly from the cylindricalsurface of the block being inclined in the direction of rotation of theplate and falling some what short of reaching the periphery thereof. [isthe plate rotated in a counter clockwise direction, viewed from. above,a limited number of coins are engaged by each feed strip as it passesbeneath the mass in the pocket, and are elevated thereby. lying Hat onthe surface of the distributing plate, and being" prevented from slidingto the center of the plate and back into the coin pocket by thehlock 82.the cylindrical sides of which mnstitute an ahutnrnt which will engagethe innermost coin on each feed strip. It will he ohseiwed that it willbe impossible for more than a single layer of coins to he thus separatedfrom the mass by the action of the feed strips shine the top face of thethinnest of the coins will be flush with or slightly higherthan theupper surfate of the ted strips, sov thatas the strip passes under themass in the pocket a coin lying above another already engaged by thestrip cannot itself be cngaged thereby. the coins which are beingcarried by the feed strips reach their highest posi tion on thedistributing plate, gravity causes them to slide down the inclinedsurface of the plate to the left of the block 92 in Figs. at and 9. isthey slide downwardly some of the coins will str the feed. strippreceding the one by which they were elevated. and will be divertedthereby toward the periphery of the plate. All of the coins even ""iththe coin re taining wall 66, along which they slide until they reach anextension 92 of the inclined marginal edge of the head til, across whichthey are delivered successively from the separating device. T he speedof rotation of the distributing plate such to cause delivery of ti ocoins from the separating device in a substantially continuousprocession. As shown in the drawings, the coins may be delivered to theprrn'i'ary' chute 9st of. a sortina' device such as that shown at of thehead (34 and the upper surface of the plate 24 are covered by a plate 98which is secured to the wall (36 on the left hand side of the separatingdevice. as shown clearly in l igrs. 4. and 9. A cover 100 of wire meshmay he provided as shown in Fi :1 to inclose the top of the coin pocket..22 and prevent possible overflowing of the coins.

.lt-is necessary to guard against the sibility of any coins, which mayfor any reason adhere to the surface ofthe distributing plate, becomingjammed between the edge of a teed strip and the outside of the wallfitl'of the coin pocket 62, and thus clogging the niechanisn'i. To thisend the distril'iuting plate is provided with a series of shallowgrooves 102 concentric with the periphery of the plate, and into eachgroove projeits a small pointed prong 104. The ron;;'s 101 extend from aplate 106 which is se'ured to the wall-U68 of the coin pocket and havethe function of dislodging the adherent coins and causing them to'slidedown the inclined face of the plate 24 and properly join the processionof othercoins. The wall 68 is cut away on its under side adjacent to thesurface of the plate 24, where it overlies the feed strips, suflicientlyto permit the feed strip to pass thereunder. Vv'hile none of the thickercoins are able to pass through the opening thus provided. for theentrance of the feed strip into the coin pocket, the dimes, and moreespecially such of them as have been worn to less than normal thickness.may possibly do so. The prong re -i. however. also performs the function of preventing the escape from the coin pocket of any dimes whichmay be thin enough to pass through this opening.

The mechanism may be operated from any Suitable source of power. Asshown an electric motor 108 drives the main shaft 110 continuouslythrough a worm 112 on the motor shaft, which engages a worm wheel 11ston the main shaft. A bevel pinion 116 on the main shaft meshes with abevel gear 118 on a shaft 120 to drive the latter shaft. T his shaft1:20. in turn. drives the vertical shaft 80, by means of which thedistributing plate Q-l rotated, through .intermeshing bevel gears 122'and 124 on the shafts 120 and 80 respectively. In addition to driving,the ver tical shaft 80 the shaft 120 also drives a crank shaft 126through a pinion 128 on the shaft 120, which meshes with a spur gear 130on the crank shaft. 'A crank arm 132 on posthe crank shaftis operativelyconnected through a crank pin 13% and. a link 136 with a lever 1.38which is iulcrumed at l lo. The connertion is made at a point 1&2between the fulcrum 14M) and the opposite end of the lever 138 whichprojects through a vertical slot 14-14 in the supporting: column 14;andis pivotally connected at l-LlG with. the lower end of a link M8, theupper end 0t which is pivotally connected at 150 with the base oi? theplunger Rotation oi the crank shaft 126 causes oscillation in a*ve'ticai plane of the lever 138 which in turn cau rcciproczu tion ofthe plunger 28. In order to provide means for conveniently connectingann disconnecting the mechanism from the main drive shaft, the bevelpinion 116 is mounted upon a sliding hub 152 which is splined to themain shaft, and an actuating rod 154 is connected with the huh throughan arm 156 and extends to a position conveniently arcessible totheoperator where it is provided with ahandle 158, in order that it may bemanipulated to control the movements of the gear 116.

Aiter the coins have been delivered by the present machine to a sorting;device. such a. that indicated generally at 96 in Fig. 1 and have beensorted and distributed to separate points, it may be desirableto countthem. For this purpose suitable counting; mechanism. not shown in thedrawings, may he associated with the sorting; device and ar'- ranged tobe driven by the main shaft of the present machine. The means hereinpro-- vided for connecting and disconnecting the mechanism oftheppresent machine with the main'shat't is of especial utility whencountingmechanism is also operated by the main shaft, since it permitsthe operation of the former mechanism to be controlled withoutinterfering with the operation of the countingmechanism. It iscontemplated that the counting mechanism may be advantageously mountedupon the table which is shown in Fig. 1 as supporting; the sorting;device' lVith .this in mind, the handle of the actu' ating rod has beenso locatedthat the opera tor will be, able to manipulate it while at thesame. time watching" the operation of the sorting and counting of thecoins.
